Abstract: A method for transporting nitride (N3−) ions in an electrochemical cell includes providing nitrogen to a first side of a solid electrolyte membrane to form nitride ions and transporting the nitride ions across the solid electrolyte membrane. The solid electrolyte membrane includes a metal nitride. The method may be used for ionically-mediated separation and/or compression of nitrogen or to form ammonia.

Abstract: Today, energy requiring equipment commonly relies on batteries for power. The excessive weight and size of batteries severely limits their performance. Described herein is a lightweight portable energy system which includes an ultra-high capacity hydrolysable hydride gel cartridge for use in supplying hydrogen gas to hydrogen based energy generators. Hydrolysable hydride reactivity is controlled by tuning the amounts of hydrophilic and hydrophobic content in a polymer gel encapsulant of the cartridge.

Abstract: An energy storage system employing a reversible salination-desalination process includes an electrochemical desalination battery (EDB) unit including an anode and a cathode. The EDB unit runs a salination process while storing energy from a direct current power supply unit, and runs a desalination process while releasing energy to an electrical load. The energy storage system can store power from a variable output electrical power supply unit such as solar cells and wind turbines while running a salination process, and release energy, e.g., during peak energy demand hours while running a desalination process. Combined with a capacitive deionization (CD) unit, the energy storage system can generate fresh water by running desalination processes in the EDB unit and the CD unit while releasing stored energy from the EDB unit. The energy storage unit can function as a dual purpose device for energy storage (load shifting) and fresh water generation.

Abstract: A system comprises an electrodialysis apparatus, which includes first and second reservoirs, wherein a salt concentration in the first reservoir reduces below a threshold concentration and salt concentration in the second reservoir increases during an operation mode. A first electrode comprises a first solution of a first redox-active electrolyte material, and a second electrode comprises a second solution of a second redox-active electrolyte material. In a first reversible redox reaction between the first electrode and first electrolyte material at least one ion is accepted from the first reservoir, and in a second reversible redox reaction between the second electrode and second electrolyte material at least one ion is driven into the second reservoir. A first type of membrane is disposed between the first and second reservoirs, and a second type of membrane, different from the first type, is disposed between the respective electrodes and reservoirs.

Abstract: A method of forming a porous structure involves mixing a solvent with a curable material which disperses in the solvent such that the mixture has greater than 50% solvent content. The mixture is deposited on a substrate and viscosity of the mixture is increased. The curable material in the mixture is cured while a shape of the curable material is maintained by the solvent. After curing, the solvent is removed from the structure.

Abstract: An electrochemical device suited to modifying a carbon dioxide concentration in an interior space includes a cathode chamber with an inlet which receives a feed gas containing carbon dioxide. A reduction catalyst layer in the cathode chamber reduces carbon dioxide in the gas to form an ionic carrier species. An anode chamber with an outlet outputs a gas comprising carbon dioxide. A solid electrolyte membrane spaces the anode chamber from the cathode chamber and transports the ionic carrier species between the cathode chamber and the anode chamber. The membrane includes an ionic liquid. An oxidation catalyst layer in the anode chamber oxidizes the ionic carrier species to form carbon dioxide. A voltage source provides a voltage difference across the membrane.
